Study on interaction effect between root and soil of apple tree

As an important organ for plant absorption, channelling, synthesis, storage, secretion, regulation, fixation and support, root system plays an important role in plant growth and development. The root system is particularly important for perennial tree trees, it is the base and center of the overall development of the tree. Although people are well aware of the interrelationship between above and below ground growth, especially under adverse soil conditions, they encounter various problems involving water, nutrients and ecology, which affect the development state of apple tree roots, and thus restrict the effectiveness of apple tree production. However, under the conditions of field production, the root system of apple trees is affected by soil physicochemical properties, biological ecological factors and their trees The combined influence of the other parts of the body shows the extreme complexity of the biological space-time effect, and The root system is distributed underground, perennial, with complex structure and huge system, which makes the observation and research more difficult It is difficult, so people's research on it is far less in-depth, systematic and comprehensive than that on the ground. Soil management measures in agricultural production work through the root system, which directly determines the development state and production level of apple trees. Therefore, this paper provides theoretical basis and technical support for the healthy and sustainable development of apple industry and fundamental guarantee for the healthy and sustainable development of apple by summarizing the research progress of the root-soil effect of apple trees. Apple trees are an important part of agriculture. With the adjustment of rural industrial structure and the opening of agricultural products market, planting apple trees according to local conditions has brought considerable economic benefits to farmers. Apple trees have strong adaptability, not only can be planted in plain areas, but also can grow in hills, deserts and other areas. Apple trees can not only increase income, but also prevent soil erosion, increase green space coverage, and regulate microclimate. In addition, the apple contains a variety of essential nutrients for human growth and development, and the apple itself and its seeds also have medicinal effects. With the development of social economy and the improvement of people's living standards, the demand for apple is increasing, and the quality of apple is also put forward higher requirements. Nutrients, water and temperature are the main factors affecting apple quality, but soil management, pruning and ecological factors also directly or indirectly affect apple quality. Among them, roots are the only bridge between apple trees and the interaction of water, fertilizer, gas and heat in the soil. The water and nutrients required for the growth and development of apple trees and various physiological active substances synthesized are completed by roots. The distribution form of roots can reflect the utilization and productivity of substances and energy in the soil by apple trees, and the root system also has the potential to improve apple quality.
